Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chestnut extractor for extracting chestnut fruits from chestnut barrels.

[0002]

2. Description of the Related Art The conventional means for taking out chestnut fruits held in a chestnut from a chestnut is to suppress the chestnuts with shoes or the like, and to pick out the chestnut fruits with a stick or a tree branch. As mechanical means, as disclosed in Japanese Utility Model Publication No. 3-5279,
A device is known in which a chestnut-bearing berry is supplied between rollers of different diameters, and the pearl is peeled off by the frictional force between the roller and the roller due to the difference in the rotation speed of the roller.

[0003]

The above mechanical means are used only for industrial processing of chestnut,
They cannot be prepared or carried at home. For this reason, for example, when picking chestnuts at the chestnut garden, or when manually picking chestnuts from the barrel at each home, there is currently no suitable tool, and the sharp needle portion of the chestnut is the chestnut. I often find it painful to remove chestnuts from the cabbage because it is easy to get stuck in my hands when removing them. Therefore, the present invention proposes a novel device for extracting chestnuts from the chestnut.

[0004]

A chestnut collecting tool according to the present invention opposes the lower part of the device so that it can be opened and closed in the left and right directions, and is always biased in the closing direction, and the facing surface is dented in the central part. It is characterized in that it is configured by a sandwiching portion having a curved surface, a restraining portion provided laterally on an outer peripheral surface below the sandwiching portion, and an opening / closing operation portion of the sandwiching portion provided in an upper portion of the device.

Further, particularly in the chestnut collecting tool described above, the restraining portion is provided so as to be movable up and down along with the sandwiching portion, and the restraining portion is provided with a ridge for urging downward pressure, or a vertical movement. It is characterized by adopting an opening / closing operation section for performing opening / closing operation of the holding section.

[0006]

[Operation] Since the gripping portion is opened and closed by the operation of the operating portion, the lower end of the gripping portion is positioned at a position where the mouth of the pearl is opened, and the gripping portion is opened while pressing down, the opening portion of the pearl is pushed and expanded by the gripping portion. At the same time, the pearl itself is held down by the holding portion, and the chestnut is located between the facing surfaces of the holding portion.When the force in the opening direction of the holding portion is released, the holding portion is closed by the urging force of the spring or the like. As it moves to, it holds the chestnut fruit, so when you remove the device from the barrel, the chestnut fruit is taken out from the barrel.
